Yes, 358 fence is highly suitable for outdoor use even in extreme weather. The heavy‑duty welded mesh (typically 4.0mm to 6.0mm wire diameter) and small 12.7mm x 12.7mm apertures provide exceptional structural integrity. To withstand rust and corrosion, most 358 fence systems are hot‑dip galvanized (HDG) or have a additional PVC coating. This makes them resistant to rain, snow, salt spray, and UV radiation. However, proper installation with galvanized posts, rails, and anti‑corrosion fittings is crucial. For coastal areas with high salinity, we recommend a double‑coated 358 fence (galvanized + PVC) to extend service life beyond 20 years. Regular inspection of coatings and drainage around posts will further enhance durability.
